Gold-Tone and Black Oval Inlay Collar Necklace

This item is a necklace, appearing to be a choker-style or collar-style piece, constructed from gold-toned metal links and featuring several oval-shaped black inserts. The necklace is composed of repeating rectangular or 'H'-shaped links, creating a flexible, perhaps articulated, chain. Interspersed along the chain are four prominent oval bezels, each housing a polished, opaque black stone or material, likely onyx, black glass, or an enamel inlay. The overall color scheme is striking, with the bright gold-tone contrasting sharply with the deep black elements. There are no immediately obvious significant condition issues such as severe tarnish or significant scratching, though minor wear consistent with age and use may be present upon closer inspection. The craftsmanship appears to be of a reasonable quality for costume jewelry, with no visible solder marks or misalignments in the links. The style suggests a mid-to-late 20th-century aesthetic, possibly 1980s or 1990s, given the bold, geometric design and the use of contrasting colors. No manufacturer's marks or signatures are visible in the provided images. The piece is designed for visual impact, with the black oval elements serving as focal points along the structured metal chain.
